Question

Im having troubles sending a variable from php to javascript.

I pull javascript (Ajax) trough this link.

<script src="<?php echo base_url().'assets/js/main.js' ?>"></script>

In my main.js :

var base_url = '<?php echo base_url(); ?>';
var language = '<?php echo $language; ?>';

Im trying to load content dynamically without refresh webpage, by using ajax .load this way:

var addressValue = $(this).children('a').attr("href");

$('#conteudo').fadeOut("slow").load(addressValue+'/index.php?idioma='+language+' #conteudo').hide().fadeIn("slow")

I can load perfectly with the addressValue onyl.
But when i try the way above, my language won’t echo.
If instead of using language i put the language i want without variable e.g. portuguese it works like a charm.
im working with multilanguage so i need to pull the content in the language the user did choose.

This is how user can set language

<ul class="nav pull-right language" id="barra_de_idiomas">
    <li><?php echo anchor(($this->uri->uri_string())."?idioma=english",'&nbsp;', 'class="language" id="en"') ?></li>
    <li><?php echo anchor(($this->uri->uri_string())."?idioma=portuguese",'&nbsp;', 'class="language" id="pt"') ?></li>
    <li><?php echo anchor(($this->uri->uri_string())."?idioma=german",'&nbsp;', 'class="language" id="de"') ?></li>
    <li><?php echo anchor(($this->uri->uri_string())."?idioma=french",'&nbsp;', 'class="language" id="fr"') ?></li>
</ul>

And my construct from controller:

    $this->load->library('user_agent');
    if ($this->config->item('language') == '') {
        if($this->input->get('idioma') == true) {
            $this->config->set_item('language', $this->input->get('idioma'));
        } elseif ($this->agent->accept_lang('en')) {
            $this->config->set_item('language', 'english');
        } elseif ($this->agent->accept_lang('de')) {
            $this->config->set_item('language', 'german');
        } elseif ($this->agent->accept_lang('pt')) {
            $this->config->set_item('language', 'portuguese');
        } else {
            $this->config->set_item('language', 'portuguese');
        }
    }
    $language = $this->config->item('language');
    $data['language'] = $language;
    $this->load->vars($data);

Answer 1

First, I suggest to you make use of base_url() like:

<script src="<?php echo base_url('assets/js/main.js') ?>"></script>

Second, you are not able to use php code in javascript files as you are doing at main.js:

var base_url = '<?php echo base_url(); ?>';
var language = '<?php echo $language; ?>';

One alternative is print the javascript variables before to main.js invocation:

<script type="text/javascript">
    var base_url = '<?php echo base_url(); ?>';
    var language = '<?php echo $language; ?>';
</script>

<script src="<?php echo base_url('assets/js/main.js') ?>"></script>
